QoS streaming based on a media filtering system

A media filter can ensure full quality media playout at the high-performance computing and communicating environment while lowering to an appropriate media quality for the smooth playout in a limited bandwidth network. In this paper, we present a new streaming architecture for the establishment of continuous media data flow over heterogeneous computer networks. Based on the new streaming architecture, we have developed a flexible and efficient audio/video transmission system. In order to eliminate heterogeneity problems found in networks, end-systems and applications, we adopt the concept of QoS media filter. The individual or receiver-driven quality of service requirement can be achieved through the application of a QoS media filtering mechanism.
